Sticky header in table (div)

URL [ http: // androidplus.ml/demo/time-table/ ]

I created a simple time table and i would like to days of the week (header) are always visible - command fixed.

I've tried with jquery.sticky.js but without correctly effect.

The first row is extended ... I don't know why:

I would like the header was hidden in a table. However, I do not know how to do it . I've tried a lot of ideas - nothing

Please help.

CSS:

     .content {
height: auto;
    max-height: 500px;
    overflow-x: scroll;
    min-width: 211px;
    overflow-y: scroll;
}
.table {
    display: table;
    margin: 0px auto;
    width: 100%;
    padding-bottom: 5px;
}
.row { display: table-row; }
.cell {
    display: table-cell;
    padding: 20px;
    color: white;
    background: #3B3737;
    font-size: 11px;
    min-width: 100px;
}
.headr {
    text-align: center;
    font-size: 16px;
    background: #A83622 !important;
    border-bottom: 4px solid #312929;

}
.days{
    display: table-row;
}
.ca{
    background: #312E2E;
}

Wrap all the rows in another div instead of everything in div.table and set overflow scroll for that div alone and margin-top:height of header.
